9903.94.51 - Passenger vehicles and light trucks that are products of the European Union as specified in subdivision (n) of U.S. note 33 to this subchapter, with an ad valorem (or ad valorem equivalent as provided for in subdivision (m) of U.S. note 33 to this subchapter) rate of duty under column 1 less than 15 percent

This HTS category, 9903.94.51, pertains to specific types of passenger vehicles and light trucks originating from the European Union. The key defining characteristics for classification under this heading are: (1) the origin of the vehicle, which must be the European Union; (2) the product type, which must be either a passenger vehicle or a light truck; and (3) the applicable ad valorem duty rate under Column 1, which must be less than 15 percent. These criteria are further elaborated upon in U.S. Note 33 to this subchapter, specifically subdivisions (n) and (m) concerning the determination of the ad valorem or ad valorem equivalent rate.

As this is a leaf node within the Harmonized Tariff Schedule, there are no direct subcategories. However, it is crucial to understand that this classification exists within the broader context of Chapter 99, which covers temporary legislation and modifications. Therefore, its application and the criteria for classification are subject to the specific temporary measures enacted under trade agreements or other legislative provisions, as detailed in the associated U.S. Notes. This contrasts with classifications under Chapters 87 and other sections of the HTS that cover motor vehicles based on their inherent physical characteristics and intended use without such temporary legislative overlays.
